node eg/sensor-temperature.js
```


```javascript
var five = require("johnny-five");

five.Board().on("ready", function() {
  var sensor = new five.Sensor("A0");

  sensor.on("data", function() {
    var voltage = this.value * 0.004882814;
    var celsius = (voltage - 0.5) * 100;
    var fahrenheit = celsius * (9 / 5) + 32;

    console.log(celsius + "°C", fahrenheit + "°F");
  });
});
